In a chat, JKR was asked how old Professor Dumbledore and Professor 
Snape were and she answered:  "Dumbledore's about 150 years old... 
wizards have a longer life expectancy than us Muggles, Snape's 35 or 
6."

So, since we know Snape and James, Lily, et all were school rivals, 
we assume they were in the same year (if not damn close).  Harry was 
about 13 or 14 in the books (in JKR's mind) at this time.  Do the 
math and that makes Lily and James about 21 or 22 ish when Harry was 
born.

album from the films because they made James and Lily look much, much 
older than they should)
